Winches are never used to hang anything. They are used for locomotion. To lift things.

If you need to hang something, you just use a hook harness. If you have a vehicle stuck in the mud or a hole, you use the winch to pull it out.

please don't hang on the word " winch " I used it because some one called it winch.

I think the mentioned pipes are some kind of lever to hold the lift on roof top when not operational and I dont see any other kind of locks to hold the platform coming from the roof or any perforation in the platform to hold a lock coming from the roof, I think its the platform which get itself hooked to the roof when it is atop.

 

[Payeng]

in this Japanese Helicopter carrier lift you can see both the safety lock (the hook) and the perforation (the hole) when the lift is not using its cables

And this thing is missing in Vicky, their should be some alternative arrangement for that.

Maybe those red plates underneath the lift

there is a braking system in the motor for the traction elevator to hold the lift on the level same as in hydraulic the valve will seal the oil to hold the lift on level and there is a mechanism called auto re-level will be activated in every few sconds to check and keep the lift on level.
good night.

check this ,this is the roping system of the traction lift in hydraulic system the motor will be replaced by a piston.while the piston moving up/down the rope pull the lift upwards and to take down the oil in the piston will be released back to the tank in a controlled manner till the lift reach the desired level.

That is the typical counterweight and pulley operated lift.

For a military vessel, I don't think one will replace the other. I believe they have a pulley as well a hydraulic system, which I had mentioned earlier. When one is being used, the other is redundant. Redundancy makes sense to me.

Not that the platform will always sits on oil lock, their should be some safety locks more then just the hydraulics, note that the landing aircraft might also touch or pass through the lift area putting pressure more then 30 tons.

Well what are this guys doing in Sevmash Shipyard's class room

Learning to speak Russian so they can read the manual.

Folks I have grabbed a bible on Aircraft carrier elevators,it is a technical manual and should be the way how US,France and Spanish carrier lifts works, hope Russian one wont be of much different.

India-China: The carrier race

China and India are neck-and-neck in their development of new-generation aircraft carriers. Both navies now have 'new' ships undergoing sea trials, and the race is on to see which will be the first to undertake landing trials for fixed wing aircraft.The Times of India reports that India's new carrier, a heavily modified ex-Soviet vessel named INS Vikramaditya which recently went to sea for the first time in its renovated state, will start aviation trials later this month. The new Chinese carrier, another heavily modified ex-Soviet vessel of so far unknown name, has now made eight sea trials, though nothing other than a helicopter is known to have landed on its huge deck.

Whoever wins the symbolic race to be the first country to land and launch fixed-wing aircraft, it is worth remembering just how far behind both countries are to the Americans. And it's not just the fleet of 11 aircraft carriers operated by the US Navy, each of which is far more powerful than the Chinese or Indian vessel. It's the 'mini' carriers that the US Navy is now introducing, the America class.

These are ostensibly amphibious assault ships, but can be configured to act as 'light' aircraft carriers. Displacing 45,000 tons and with the ability to carry 20 strike aircraft, they will actually be around the same size as India's new carrier and arguably more capable than either the Indian or Chinese vessel.

On the other hand, Morris Jones' words on The Interpreter last week should also be kept in mind. Reports that China is decades behind the US in space technology 'fail to account for the "leapfrog" effect of technological advances, and the benefit of experience from other nations. Such effects are propelling much of Africa from being disconnected from telecommunications to enjoying broadband wireless services in just a few years. The effects are just as significant for China's space missions.'

Indian Navy tests out new trump card

The Indian Navy's new aircraft carrier Vikramaditya – formerly the Soviet heavy aircraft cruiser Admiral Gorshkov – is undergoing tests in the White Sea. The ship is to return to India by the end of the year.

The heavy airborne cruiser Admiral Gorshkov, built in Nikolaev as part of Project 1143, was the fourth and last Kiev class ship. The story of this family of aircraft carrier ships began in the 1960s when, after Nikita Khrushchev's resignation, the USSR resumed creating a large surface fleet.

These heavy aircraft cruisers have a complicated background. Their design was the result of many compromises between the Ministry of the Shipbuilding Industry, the military command, seamen and the Soviet political leadership. The fleet expected to get universal combat ships which were cheaper than the US Navy's combat aircraft carriers. The air wing was to consist of Ka-25 anti-submarine helicopters, and Yak-36 (Yak-38) vertical take-off and landing aircraft.

Many specialists and naval history enthusiasts are still uncertain about their purpose: some consider them to be fighters; others low-flying attack aircrafts. Yet as fighters they were lagging behind their "classmates", such as the British Harriers – not to mention the normal MiG-23s, Phantom, etc. Indeed, as low-flying attack aircraft they were at a disadvantage to virtually all then-contemporary winged combat craft of the world's leading countries.

At the same time, due to the Yak-38's unsatisfactory combat capabilities it was decided to strengthen the ship's arsenal by equipping it with anti-ship missiles. The construction of the cruisers for Project 1143 began in July 1970, when the head ship Kyiv was laid down at the Black Sea shipyard in Nikolaev. The fourth ship of the project, Baku (the future Admiral Gorshkov), was laid down eight years later.

The collapse of the USSR ruined plans for modernizing the aircraft carrier, according to which she was to receive the latest Yak-141 vertical takeoff and landing airplanes (VTOL). In 1992, the Gorshkov was docked for repairs, and since then she has never been put into operation again. In February of 1994, two major accidents occurred on board the cruiser in succession: a fire, and a steam pipeline explosion. After that, putting the ship back into service was out of the question.

Talks about the ship's possible sale to India began back in the late nineties. At that time, plans were discussed of her transformation into a classic aircraft carrier equipped for carrying 20-25 MiG-29 aircrafts. The contract for the sale of the aircraft carrier was inked in 2004. According to its terms, Russia was to supply the ship and a group of carrier-based fighters to India, and to train its crew for the sum of $1.5 billion. The Gorshkov carrier was renamed INS Vikramaditya in the Indian Navy service in honor of one of the country's historic heroes. The architecture of the modernized Gorshkov is reminiscent of the Admiral Kuznetsov, albeit on a smaller scale.

Interest in the project grew stronger in the summer of 2007, when the default on contract was announced. Initially the ship was to be handed to India in 2008, but works were prolonged till 2010. A wrong assessment of the amount of work needed on a number of the ship's onboard systems, and the undervalued price of her modernization were named as reasons for the failure.

In the Indian fleet, the Russian-made ship is to replace the Viraat aircraft carrier – the former British Hermes built in 1959, and bought by India in 1985. In 2010, the Viraat's term of service had already reached 51 years. The Gorshkov was built in 1987. It is interesting, therefore, what fate awaits her in 2038?

It is impossible to answer this question, but it is clear that today the ship is a real trump card for the Indian Navy. The Gorshkov with MiG-29s on board provides the Indian Navy superiority over all its neighbors, including its eternal rival Pakistan. The possible capacities of Chinese ships are uncertain. First of all, there are doubts that the Chinese aviation industry is able to create a full-fledged deck fighter using the Soviet SU-33 bought in Ukraine as a prototype.

As a result, the only navy in the region significantly superior to the Indian Navy is the US Navy. At the same time, the United States desperately needs Indian support in a possible confrontation with China.

It can only be guessed, then, upon which side India's trump card will fall.

PLATFORM LOCKBARS. The purpose of the platform lockbars is to secure the platform at the
flight deck. The lockbars are generally ganged together and are actuated hydraulically or pneumatically. The
lockbars are capable of supporting the weight of the platform loaded to its rated capacity, plus snow and ice loads
and dynamic forces caused by storm conditions. The platform lockbars must be retracted before initiating any
platform movement. The mechanical interlocks prevent extension of the lockbars unless the platform is at the
flight deck. Electrical interlocks prevent elevator operation when the lockbars are extended.
